The Telegraph Operator's Challenge - 5.RI.1-4 & 5.NBT.5/6

Front

One morning, Emma received a message requesting 1,560 barrels of flour to be delivered to a supply depot to feed Union soldiers. Each wagon could carry 24 barrels. How many wagons were needed to transport the flour?

Emma then faced another challenge. The station had only 5 hours before the wagons were scheduled to depart. Workers could load 32 barrels per hour onto each wagon. She needed to determine if they could load all 1,560 barrels in time.

Back

To find out if they could load all 1,560 barrels in time, we calculate the total loading capacity. In 5 hours, they can load 5 hours * 32 barrels/hour = 160 barrels per wagon. If there are multiple wagons, we need to know how many wagons are available to determine if they can load all barrels.
